Peanut underground fertilizer with effect of increasing yield at early stage

Abstract

The invention discloses a peanut underground fertilizer with an effect of increasing yield at an early stage. The fertilizer is characterized by comprising the following components in parts by weight: 10-20 parts of corn straw powder, 15-25 parts of nitrogen, phosphorus and potassium compound fertilizer, 6-8 parts of humic acid, 8-10 parts of itaconic acid, 1.5-2.5 parts of trace elements, 0.2-0.5 part of growth regulator and 40-60 parts of water. The chemical fertilizer utilization rate and the grain number at the later stage can be increased by adopting the prepared fertilizer, so that the yield is increased and the quality is improved. The fertilizer has good efficiency and strong pertinence, is quick in nutrient absorption and makes up for the deficiency of roots in nutrient absorption. A fertilizer application method is simple and practicable and has obvious economic benefits.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to an early-stage groundnut fertilizer for increasing yield. Background technique

[0002] Mainly farmyard manure, supplemented by chemical fertilizers. In my country, peanuts are mostly planted in hilly areas with thin soil layers and low fertility. Farmyard manure is mainly organic fertilizer, which is rich in nutrients and can improve the soil. Chemical fertilizers are quick-acting fertilizers. Although they also contain the nutrients needed by peanuts, compared with farmyard manure, the nutrients are still single. At the same time, during the application of chemical fertilizers, other components remain, which is not conducive to the growth of peanuts and the improvement of soil fertility. Organic nitrogen, phosphorus, and potassium underground fertilizers can improve the activation of microorganisms in the soil and the decomposition speed of organic fertilizers...
